 This tutorial describes how to perform static timing analysis (STA) on a circuit which has
 been implemented by :ref:`VPR` using OpenSTA, an external timing analysis tool.

 External timing analysis can be useful since VPR's timing analyzer (Tatum) does
 not support all timing constraints and does not provide a TCL interface to allow
 you to directly interrogate the timing graph. VPR also has limited support for
